Abbott Workholding HOW27M88S Soft Lathe Chuck Jaw Serrated

Product Description

The ABBOTT WORKHOLDING PRODUCTS HOW27M88S is a serrated soft lathe chuck jaw machined from 1018 steel, designed for use in manual and CNC lathe chuck assemblies. Soft jaws are field-machinable, allowing technicians to bore custom grip profiles for precise workpiece control. This jaw measures 4 inches in overall length, 2 inches in overall height, and 1.5 inches in overall width. The serrated interface pattern locks positively into compatible chuck bodies, resisting jaw shift under cutting loads. A set of three jaws is included, matching the standard 3-jaw chuck configuration found across most production and toolroom lathes.

This jaw is suited for metalworking shops, machine tool maintenance environments, and production turning applications. It fits chucks up to 8 inches in maximum compatible diameter. The serrated interface and square jaw shape make it appropriate for general-purpose gripping of round, hex, and irregular stock. Machinists and tool-and-die technicians typically install these jaws during chuck rebuilds, soft jaw replacement cycles, or custom workholding setups requiring bored or turned grip surfaces.

Installation Notes

Installation is performed by qualified machinists or tool-and-die technicians. Disengage the lathe from power and lock out the spindle before removing or installing chuck jaws. Confirm that jaw slot width and mount hole spacing match the chuck body specifications prior to assembly. After installation, verify jaw seating and torque fasteners to the chuck manufacturer's specifications using calibrated tooling.
